Genesis Tripmeter 3.8L, 2011

[marli]

I have seen numerous posts regarding the tripmeter elapsed time, mpg, mph, etc. resetting.
I have this problem and have finally convinced my dealer to bring this to Hyundai's attention and I have spoken with Hyundai and a case has been opened.
The Elapsed time does reset after a time period or overnight - Fact
It appears to me that after collecting data that the mpg and mph also reset or start recalculating from a new and therefore does not represent the true mpg or mph.
What good is a tripmeter if not meaningful, accurate and controlled by the owner?
Note that the manual states that these are only reset manually (by the owner) unless you fill up with gas.
Hyundai should now be aware of this even though they tell me as well as my dealer that they have never know about this before. With the numerous posts I find that hard to believe.
Hopefully Hyundai will take this seriously and issue a software upgrade to correct it.
In the meantime any Genesis owner who has this problem should definitely report it to your dealer and have them verify it and then push them to push Hyundai to correct it. If we owners do not push our dealers and Hyundai we have little chance of resolving this.

I am a little confused. Exactly what is the problem? I can reset my MPG anytime I want by holding down the reset button several seconds while displaying the MPG. I have not tried to reset elapsed time or average speed. MPG is not reset unless I fill tank or reset manually.

 

[tompass]

Should be able to manually reset the mileage and mpg for trip A without it affecting trip B. This would be you an average over many weeks and fill ups.

 

[rwlewis]

You need to specify which package you have on the 3.8.

Base
Premium
Premium w/Touch Nav
Tech (DIS Knob)

Also, please describe the actual issue you are having and how to easily replicate it...so that others can try to replicate it...

I have 2011, 3.8 Premium+Touch Nav. I have not seen any quirks related to the trip computer, but have not really used them in detail....the MPG seems to reset @ fillup. Trip A & B reset manually as expected. Never used really look at the ET or average speed, but I know I can manually reset them.

It appears to me that after collecting data that the mpg and mph also reset or start recalculating from a new and therefore does not represent the true mpg or mph.


Are you suggesting the MPG calculation rests each time you start the car without any driver intervention?

This should only occur under two scenarios:

1) Purchase of Gasoline

2) Manually resetting of the reading by the Driver

 

[marli]

No, this is what I am saying.
1.) Elapsed Time, mpg, and mph are not separate for Trip A and Trip B but record the same information. The odometers on Trip A and Trip B are independent so resetting one does not reset the other.
If you reset Elapsed time, mpg, or mph under Trip A, you will note that it also
resets under Trip B. Those are not my concerns though.
2.) If you will monitor the Elapsed time, on my vehicle the Elapsed time automatically resets to 0.00 after something like 3 or 4 hours of being parked and definitely overnight. Check your Elapsed time in the morning to see what it actually reads.
3.) As far as the mpg and mph, the data I collected indicates that they are either being reset automatically or recalculating when you start the vehicle and do not indicate a true mpg or mph over an extended period of time.
4.) My dealer has finally acknowledged that my vehicle reset the Elapsed time, the loaner they gave me does, and the vehicle the Service manager took home overnight does so I believe it is prevalent to all Genesis and is a software problem.
5.) If my concern regarding mpg and mph is correct and I believe it is these are my thoughts.
If you drive to work in the morning and then drive to say a ballgame and then drive home, you have made 3 separate trips.
Now ask yourself, is your avg mpg and avg mpg for the whole day (all trips), for only the last two trips of the day, or just for the last trip of the day. I wonder.
Check it for yourself and see what you are seeing.
6.) The owner's manual definitely states that the Elapsed time, mpg, and mph are reset by the operator with one exception. Mpg resets with a fill up.

Test these for yourself and see what your results indicate.
I doubt that since my 2011 3.78L w/Tech operates this way that yours might also. I do not believe Hyundai would have separate software packages for these.

 

[Mark_888]

1). Yes, there is only one MPG and Elapsed Time counter, which are independent of the 2 trip odometers.

2). Yes, we know that. So what?

3). MPG does not reset unless you fill tank or manually reset. I assume that average MPH resets with Elapsed Time of last trip, which resets after a few hours.

4). Yes, it works that way, and no, it is not a problem because it is working as designed. If you have a problem with that, I would recommend you buy a watch.

5). Average MPG is for the entire time until you refill tank or manually reset. I believe that average MPH is for each trip, which gets resets after a few hours of idle time.

6). That means that these can be reset by the operator, not that they don't get reset some other way. Remember that some person in Korea translated the manual to English, and may have not been totally clear due to it is not their native tongue, or someone in the US translated the manual from Korean and did not completely understand the Korean version.

 

[marli]

Mark_888 must be a genius or a Hyundai employee.
Since neither the dealer nor Hyundai California could explain how the system works.
I am not sure, but I believe the owners manual is suppose to clarify how the system works. I don't care if it was translated or not someone should be checking it for accuracy.
So, since you seem to know everything, what is the time period that elapsed time is reset on ?
So, I cannot get a total elapsed time from fill up to fill up nor can I get an avg mph from fill up to fill up according to you.
Now, when I make a 3-1/2 hour trip and avg. 59 mph and then 3 hours later drive around the neighborhood and get and avg. 8 mph how does that avg from fill up to fill up.
If you are sticking to what you are saying, maybe you should inform Hyundai so that Hyundai can explain it to its customers.
I for one would like to get a total elapsed time, avg mpg, and an avg mph from fill up to fill up if that is actually what is going on. The system does not do that so I don't even know how long the driving time is if the trip is done over 3 days without a fill up. Maybe you do.
I do have a watch, but I do not read and record the time everytime I stop and start the vehicle. The vehicle should do that for me.

 

[tompass]

But why is it when you reset the mpg for Trip A, the mph for Trip B is also reset? That should not be because with most other cars, they are separate functions.

 

[mikec]

On the Genesis the trip odometers are separate functions from the rest of the displays/computations. There are not separate Average speed, time, MPG, etc. computations/displays for the two trip odometers - i.e. you can't have a "running total" MPG for two different trips/segments. Basically you have:

* vehicle odometer
* Trip A
* Trip B
* Average Speed
* Elapsed Time
* Average Fuel Consumption (MPG)
* Instantaneous MPG
* Estimated distance to empty

Obviously the odometer has no "reset" mode!

Trip A & Trip B reset individually ONLY when the "TRIP" button is held down for more than a second while displaying either Trip A or Trip B. They should not reset when the vehicle is parked/shut off nor when the gas tank is filled. Personally, I reset Trip A whenever I fill up with gas and use Trip B for monitoring trip/driving distances. Each time I fill up, I check/compare Trip A to my "history" to see if things are getting better or worse - it's a way to spot fuel leaks (that won't show up in the average MPG display) or when California changes fuel blends, etc. I know the approximate number I should see at each fill-up (for all of my cars) so this is a way I can monitor the health of my vehicles. The other cars don't have running MPG displays like the Genesis so a total distance traveled since last fill-up is what I use.

Average Speed computes since the "last average speed reset" which is either holding the RESET button down for more than a second OR having the vehicle OFF for more than a couple of hours. The exact time is not specified in the owners manual. Basically the system tries to accumulate average speed while the engine is ON (even if you're not moving) for what the car thinks is a single journey; a "single journey" may include short engine-OFF stops (i.e. filling up with gas or stopping for lunch)... after you park for a few hours the car decides "we've arrived... that journey is over, next time the engine is ON it's a new journey." Resetting either Trip Odometer won't affect the Average Speed either since the Trip Odometers are totally independent of the rest of the system. The Average Speed does not measure time to the last time you filled the tank days ago; it only monitors a single journey.

Elapsed Time operates similar to Average Speed. It accrues for a "journey" but doesn't count engine-OFF time for short intervals (gas fill-ups, lunch again).

Average Fuel Consumption resets when the gas tank gets 1.6 gallons or more of fuel AND the vehicle has started moving again. Or when you hold RESET for more than a second with MPG displayed. The Average Fuel Consumption should compute across multiple "journeys" too - if you want separate average MPG readouts for the highway drive to wherever, and then the putt-putt driving at wherever you'll have to read/note the MPG when you arrive... then hold RESET to re-zero the MPG computations before you do your local putt-putt driving.

The remaining two functions don't have a "reset" to worry about; they are continuously updated readouts.

That's how the 2009 owner's manual says the system should work and that's how my 2009 V8/Tech sedan operates. It's probably different from a Maxima or some other car, so what? The Genesis doesn't answer the question "how many hours have I driven on this tank of gas" as marli seems to need/desire.

And if your "journey" seems to not reset properly - i.e. the car thinks it's been on one journey since the day you bought it, then THAT is a problem. I'll bet the rubber pad hanging from the mid-point of the driver's side hood edge is missing or not properly pushing on the alarm switch in the fender... so the car thinks "hood is open" all the time. "Hood is open" leads to a weak/dead battery after just a day or two AND it keeps the Genesis electronics in "ready" mode - a "journey" is still on-going. So journey-specific things never reset because the journey never ends!

I understand that but if you wanted to get average mpg over several tanks of fuel, it is not possible on the Genesis. My previous car was 12 years old and that function was possible. Seems it is something that Hyundai engineers should consider addressing. It would be very useful.

 

[marli]

I agree with Mike C in regards to the odometers for Trip A and Trip B.
I also agree with tompass in that it would be nice to get a mpg over multiple fill ups.
I guess the real problem comes down to how one defines a "Trip" and the fact that Hyundai has taken it upon itself to arbitrarily define it by using a timer to
reset the elapsed time and mph and I still have concerns about whether they do the same with mpg.
Hyundai either needs to just reset everything when you turn the engine off and define that as a trip or at the very minimum tell us what time they have programmed in to this system where they arbitrarily reset elapsed time, mph, and my concern mpg.
Resetting everything when the engine is turned off is a clean break and everyone can understand that.
Using a timer (arbitrary as it is and unknown to us) leaves us wondering what we are actually seeing.
If Hyundai's arbitrary timer resets the Elapsed Time and the Avg. MPH, then I would need to look at the Elapsed Time every time I start the vehicle and make a decision as to whether what I read for mph is starting from that time or accumulating from the last trip. Nothing more than confusing.
Get rid of the timer and just reset every time the engine is turned off or just make it all a manual reset to the maximum allowed time 99.99 so the owner can make full use of the system.
As is presently stands, I don't believe anyone can interpret the data accurately until the timer is removed.

My comments below are based on my 2009 non-Tech Package Genesis:

Mark_888 must be a genius or a Hyundai employee.
Since neither the dealer nor Hyundai California could explain how the system works.

I don't want to make any claims about my intelligence, but I am definitely not a Hyundai employee (you must be relatively new here). My understanding of how it works is based on observation, and in some cases other threads previously in this forum.

I am not sure, but I believe the owners manual is suppose to clarify how the system works. I don't care if it was translated or not someone should be checking it for accuracy.

Well, if we were in Singapore, we could cane the people who wrote/approved the Owners Manual. If they refused to be extradited from Korea, we could force someone from HMA to stand in their place. Maybe someone from HMA wrote the English version of the manual.

So, since you seem to know everything, what is the time period that elapsed time is reset on ?

If your car sits idle for a few hours in-between fill-ups, that is correct you cannot get it. I don’t know where that is documented, I think I observed the behavior by the Genesis computer, and also other people have mentioned it on this forum. It appears that if you are on a trip, and stop for food, etc, the counters don't reset, but if you stop for several hours they assume you are on a new trip.

So, I cannot get a total elapsed time from fill up to fill up nor can I get an avg mph from fill up to fill up according to you.

Not if your car has been idle for several hours in-between fill-ups.

Now, when I make a 3-1/2 hour trip and avg. 59 mph and then 3 hours later drive around the neighborhood and get and avg. 8 mph how does that avg from fill up to fill up.

The averages are reset after a few hours of idle time, so you cannot get that from what I understand.

If you are sticking to what you are saying, maybe you should inform Hyundai so that Hyundai can explain it to its customers.

I try to spend as little of my life talking to car salesman, automobile service managers, or automobile marketing people as possible, and I don’t have time to lecture them about all the things they don't know. From what I can tell, they only know enough information needed to sell a car (or sell some service) and then their minds go blank.

I for one would like to get a total elapsed time, avg mpg, and an avg mph from fill up to fill up if that is actually what is going on. The system does not do that so I don't even know how long the driving time is if the trip is done over 3 days without a fill up. Maybe you do.

Doesn't look like that is possible just using the built-in electronics.

I do have a watch, but I do not read and record the time everytime I stop and start the vehicle. The vehicle should do that for me.

You can get a chronometer (stop) watch, or a small kitchen timer that will do that, although not automatically.

Could I make a suggestion? Your posts are brutal to read. Try putting some white space in them. Mike C's post above is an excellent example.

 

[marli]

It really gets down to how you define a trip.

I don't consider a 10 minute trip to the grocery store a trip and am not concerned about time, mpg, mph in these cases but I would like to have this information for a day or week at a time without trying to dechiper if
anything has arbitrarily reset.

But if I am to take a longer trip say to Florida, Texas or whatever I would like to know the total driving time without purchasing the chronometer you mention. I also would like to know my avg mpg and avg mph for that trip.

I cannot interpret data if I have to first check every time I get into the vehicle to see if this reset or if that reset and then say oh this is an avg over my last two trips or no this is the avg for just this trip and I doubt that you could either.

Lets just say that if Hyundai had not put an arbitrary timer in there and had not decided to reset on fill ups and allowed the owners to decide for themselves then we would all understand what it is we are reading and at the same time give us the tools to evaluate avg mpg in relationship to avg mph, total trip time, etc., etc. and then have some meaning.

Let's also state that anyone familiar with the software could in a manner of less than 5 minutes correct it and give us a software upgrade. Then the TSB issued could be installed for anyone who feels the tripmeter does not serve their purposes and those who are happy with the way it operates will then still be happy. Except for Safety TSBs and maybe some others, usually they are not installed until the owner questions it and they find that a TSB has actually been issued.

For some reason you seem to be hung up on elapsed time which I consider important for an extended trip, but what about your concerns for mph and mpg over that extended period. Wouldn't it be nice to know this.

Again, I will state that no one from Hyundai has been able to explain this operation so I am only stating what I have seen and what the manual states.

 

[marli]

These will be my final words on the tripmeter.

What we know:

1.) Both the Elapsed Time and MPH are reset on some arbitrary timer in the program and no one knows what that time is.
2.) That the avg mpg is reset to zero after filling up with fuel.

If a manual reset IS NOT DONE on Elapsed Time, MPH, or MPG prior to a trip then:

1.) I am not guaranteed an accurate reading on total time elapsed, mph, or mpg for that day or for that week.
(This is because maybe the timer reset the Elapsed Time and MPH while parked during that time period or maybe I filled up with gas during that time period)

2.) I am not guaranteed an accurate reading on total time elapsed or mph on even a short trip.
(This is because I do not know whether the timer has automatically reset these items and whether what I am reading is an accumulated figure taking into account a previous trip or a newly calculated figure from the beginning of this trip. To know that you would need to check these figures before you even start that trip.)

Here is what I am guaranteed.

If I manually reset Elapsed Time, mpg, and mph before starting a trip or journey and I do not stop to fill up with gas then these readings should be accurate when I complete that journey or trip and turn the engine off.

So to be assured of accurate readings I must manually reset everything prior to the trip and must read everything once I stop the trip and the engine is turned off.

What a great trip meter.

 

[Mark_888]

There are a lot of things they could have done better on the trip computer. My biggest complaint is that the trip odometers only go up to 999 miles (on my 2009 Genesis), and on other cars I have owned I used the trip odometer to track miles between oil changes. Maybe we will see some improvements when the Genesis is totally redesigned (I assume in a couple of years).

But compared to other concerns I have had about my Genesis (2009 suspension, throttle body sensor, etc), the issues with the trip computer are relatively minor (for me personally).

 

[marli]

We will only see changes if we question what we presently have. If everyone is satisfied with the tripmeter's present operation why would Hyundai spend the 2 minutes to fix their programming.
Things only get changed or done when brought to light or when numerous people are asking the same question.
Fixing something you don't know about very seldom happens.

 

[NYCGPS]

I'm not sure about the Genesis or Hyundai in general. Hell I don't even own a Hyundai yet ---- (looking forward to)

but on my 2010 Mazda3 Hatch, the Trip A/B are separated. resetting one will not effect the other.

and the "average mpg" numbers will not reset itself ---- only if you manually do it.

Same thing goes for my Brother's 2009 Infiniti FX35

I think there is a difference between making suggestions to Hyundai about the trip computer for the next version of the Genesis, versus demanding that they change units already sold. Obviously, if something is clearly broken, that would be a different story, but misleading info in the Owner's Manual doesn’t necessarily mean that the trip computer is broken.

Also, keep in mind that the Genesis is a Korean car, sold in several places around the world, and that Hyundai Motor America does not have control over everything (although they did specify their own suspension tuning for North American versions).

 

[marli]

I never stated that it was broken but only that it does not operate in accordance with its published manual.
Even though I disagree with how the tripmeter (Elapsed time, mpg, mph) should operate, I would be satisfied and say maybe Hyundai will correct it in the future if only it did operate in accordance with the manual which it does not.
As you can see, some of the other post regarding various vehicles do not reflect a timer and also state the mpg are not reset until reset manually.
Maybe they have it right.
As far as being sold.
When you purchase something and it does not operate as expected or as advertised or as stated in the manual but is NOT BROKEN do you simply accept it or do you return it or question it ?
I wonder.
I really do not understand your defensiveness in this situation.
I am simply questioning it and probably whomever in their infinite wisdom decided that an arbitrary timer was what was needed. Needed for what ?
The What and the Why is what I am asking.
